Electroless Nickel Plating

Entech specializes in providing unparalleled electroless nickel plating services. We ensure the even application of high-quality nickel-phosphorous coating on all kinds of components without resorting to external electrical current. This makes it ideal for parts with complex geometries, internal features, and tight tolerances. 

With our electroless nickel coating services, you can expect: 

• Even application of uniform thickness across all surfaces
• Superior corrosion resistance
• Predictable wear performance 
• Enhanced lubricity of moving parts 

What is Electroless Nickel Plating

One of the most distinctive features of electroless nickel plating is that it requires no external electrical current to get the job done. It is an autocatalytic plating process that applies an even nickel-phosphorus alloy coating to metal, alloy, and non-metal substrates. 

Electroless nickel plating works will with the advanced masking techniques that we employ. Advanced masking covers specific areas of components, ensuring only the required surfaces are plated. Electroless nickel plating process works by dipping the components in a solution containing: 
 

• Nickel salt
• Phosphorus (containing a reducing agent)

Unlike traditional electroplating, where reaching internal surfaces is generally difficult, electroless nickel plating works great with complex parts that have intricate geometric patterns. Electroless nickel plating is the go-to choice for precision-machined components in industries such as:
 

• Aerospace
• Automotive
• Industrial Manufacturing
• Medical
• Energy
• Oil & Gas
• Plastic
   

Key Benefits of Electroless Nickel Plating

The popularity of electroless nickel plating among manufacturers across Canada and the United States can be attributed to the following benefits:

Uniform Coating
Electroless nickel plating ensures uniform coating by covering the internal and external surfaces equally.
 

Impressive Corrosion Resistance
Nickel-phosphorus coating offers unmatched corrosion resistance, making it ideal for critical components that demand longevity.

Improved Wear Resistance
Electroless nickel plating provides a thick, strong coating that protects components from general wear and tear.
 

Ideal for complex geometries
Since uneven current density is removed from the equation, electroless nickel plating offers consistency for components with complex geometries.
 

Enhanced lubricity

The smooth, non-porous surface texture of electroless nickel plating minimizes friction and enhances lubricity. 

Supported Industry Specifications

At Entech, we take pride in consistently meeting and exceeding engineering standards. Our process guarantees the highest safety and performance of components across crucial industries. Supported specifications include:

ASTM B733: Defines required precision levels such as thickness, uniformity, composition, and performance for electroless nickel-plated components.

ASTM F86: Widely demanded in the medical and healthcare industry. The ASTM F86 is the surface preparation requirement for metallic surgical implants and other biocompatible components.

AMS 2404: This is an important industry specification that aerospace components must meet. AMS 2404 specifically pertains to electroless nickel plating with controlled phosphorous content.

AMS 2405: This is the highest industry specification for electroless nickel plating with higher phosphorous content. This specification denotes higher corrosion resistance.

AMS 2403: Specifying requirements for electroless nickel plating with low-phosphorous coating, AMS 2403 is an important specification that denotes impressive hardness and wear resistance.

MIL-C-26074 / AMS-C-26074: An important military specification that is mandatory for components used in aerospace, defence, and other critical industries.

Electroless Nickel Finish Options

There are primarily three electroless nickel finish options, each depending on the phosphorous levels. Depending on the desired results, you can choose from these three electroless nickel finish options:

High Phosphorus Electroless Nickel

Ideal for applications where the components must:

• Possess maximum corrosion resistance
• Survive harsh environments
• Deal with moisture exposure

Medium Phosphorus Electroless Nickel

Ideal for applications where components must possess:

• Perfect balance of hardness and corrosion resistance
• Seamless cosmetic finish

Low Phosphorus Electroless Nickel

Ideal for applications where components must possess:

• Impressive hardness
• Wear resistance
• Solderability

Industries Using Electroless Nickel Coatings

A wide range of crucial industries relies on electroless nickel coatings to increase corrosion resistance, hardness, and durability of components. These industries include:

 

Aerospace
Aerospace parts and components must perform in extremely challenging conditions.

To adhere to the highest safety and performance standards, aerospace components are plated using ENC. 
 

Industrial manufacturing
Whether for improving the lifespan of tools or preventing friction, industrial manufacturing greatly benefits from electroless nickel coatings. 
 

Automotive
Since automotive parts are constantly exposed to fuel and oil, it must possess impressive durability and efficiency. ENC guarantees exactly that.
 

Medical devices
Medical devices must be biocompatible. Electroless nickel plating that meets ASTM F86 standard ensures a smooth finish and hygiene.
